STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 408,573, dated August 6, 1889.

- Application filed January 31, 1889. Serial No. 298,171. (No model.) I

To all whom it may concern:

Be it known that I, EDWARD K. BOYD, a subject of the Queen of Great Britain, residing at Chicago, in the county of Cook and State of Illinois, have invented newand useful Improvements in Pendant finding and Setting lVatches, of which the following is a specification.

This invention relates to an improvement in stem winding and setting watch es; and the object of this invention is to secure a mechanism which will be simple in its operation and of durable construction, as set forth in the following; specification and claims and illustrated in the accompanying drawings, in

which- Figure 1 is a face View of stem winding and setting mechanism. Fig. 2 is a view similar to Fig. 1, with parts in a different position than in Fig. 1. Fig. 3 is a section along the line x :10, Fig.1. Fig. 4 is a detail view of a spring. Fig. 5 is a section along the line 11 y, Fig. 1. Fig. 6 is a detail view of a lever. Fig.

7 is a plan View of a pinion. Fig. 8 is a side elevation of Fig. 7. Fig. 9 is a side elevation of a shank. Fig. 10 is a side elevation of stein-arbor.

Similar letters indicate correspondin g parts.

In the drawings, the letter A indicates a watch-case.

B is the pendant, and O the ring.

The crown D is adapted to rotate the stemarbor E, so as to wind or set the watch.

The pendant B has a recess or housing to receive a spring F. The spring F, as seen in Fig. 4, is readily made from a single piece of wire and has an eye G for the passage of the arbor E. Said stem-arbor 'E is capable of a certain lengthwise movement and has two stops II II, Fig. 10. \Vhen the stem-arbor E is moved lengthwise until one stop is engaged by the spring F, as seen in Fig. 1, the mechanism is in position for winding by the rotation of the stem-arbor. W hen said stem-arbor is moved lengthwise until the other stop is in engagement with the spring F, as seen in Fig. 2, themechanism is in position for setting by the rotation of the stem-arbor. The lengthwise motion of the arbor E is secured by moving the crown D inward or outward until the spring F snaps into engagement with one or the other of the stops 11, whereby further lengthwise motion of the stem-arbor,

in such direction is prevented. The rotation of the stem-arbor E is secured by turning the crown D. To the pendant B is secured acappiece I, which retains the spring F in its housing.

The stem-arbor E has a square or angular shank K, Fig. 10, which sits into a corresponding socket in the head L of the shank M. Said shank M is square or angular and sits into a corresponding socket in the pinion N. The stem-arbor E and shank M are thus free to move lengthwise a certain distance independently of one another and of the pinion N while remaining in engagement, so that the rotation of the stem-arbor E will rotate the pinion N. The head L has a recess 0, into which sits the lip P of the arm Q of lever Q R. The gear-wheel S, mounted in the yoke T, is engaged with the pinion N. Said yoke T has a tooth or shoulder U.

When it is desired to adjust the meehan, ism from the winding to the setting positionthe crown D and stem-arbor E are moved outward,- whereupon the spring V moves the lever Q R from the position shown in Fig. 1 to the position shown in Fig. 2. By this motion of the lever Q R the lever-arm R is caused to press upon the tooth U, so as to move the yoke T to the position shown in Fig. 2, in which position the gear-wheel Y is in gear with the setting mechanism. In this posit-ion the lever-arm R sits against the tooth U, so as to hold the yoke T in the position shown in Fig. 2. To adjust the mechanism from the setting to the winding position,

the crown D and stem-arbor E are moved inward, whereby the lever Q R is moved back to the position shown in Fig. 1, thus compressing the spring IV, whereby the yoke T is pressed back to the position shown in Fig. 1.

The gear-wheels X Y are mounted in the yoke T and gear into the wheel S. When the crown D is rotated, the motion is communicated through the stem-arbor E and pinion N, so as to rotate the wheels S X Y. In Fig. 1 the gear-wheel X is in gear with the wheel Z of the winding mechanism, and when in this position the crown D is properly turned IOC the watch will be wound up, the wheel Y meanwhile rota-ting idly. IVhen the parts are in the position shown in Fig. 2, the gear- Wheel Y is in. gear with the wheel a of the settin g mechanism, and when in this position the crown D is turned one way or another the watch is set forward .or baelnvard, the gear-wheel X meanwhile rotating idly. The yoke '1 can be made easily movable by being suitably mounted on a stud or axle I), while a stop 0 can be arranged to properly limit the swinging of the yoke.

The lever (Z c is adapted to lock the yoke T in the winding position. This lever is of use, for example, if the movement is out of the case, as during cleaning or repairing, since said lover (I 6 can then be used to prevent the yoke from accidentally moving to the setting position. To look the yoke by means of the lever (Z a, the arm eof the lever is moved by a finger or tool, so as to press the arm (Z against the yoke '1, thus holding the gear-wheel X in gear with the wheel Z.

The lever-arm It, as already noticed, not only moves the yoke 'l. to the setting position, but also looks said yoke in said position by the free end of the arm R sitting squarely against the tooth or shoulder U, Fig. 3. \Vhen moved to the position shown in Fig. 1, the arm R is moved to the deep or recessed part of the tooth U, so as to leave the yoke 'l free to move to the winding position.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

1. In a watcl'i-moveinent, the combination, with an actuating-arbor made adjustable to and from the winding and setting position and provided with shoulders or stops I I ll, oi. a spring adapted. to engage said stops to hold the arbor in position, said spring being fOlll'lQtl of a single piece of wire and having an eye for the reception of the arbor, substantially as described.

2. In a watch-movement, the combination, with a stem-arbor E and intermediate shifting head L, having an angular opening for the shank of the stenrarbor and provided with an angular shank M, passing into the winding-pinion N, of a lever eom n'ising two arms Q and B, one of which engages the shifting head, and the swinging yoke 'l, having the tooth U to engage the other arm ot' the lever substai'ltially as described.

3. In a watch-movement, the comljnnation, with a stem-arbor E, an ii'itermedizitte shift ing head L, a winding-pinion N, and a lever comprising two arms Q and R, one of which engages the shifting head, of the spring V for the lever and the swi ngin g yoke T, havin a tooth U to engage the other arm of the lever, substantially as described.

l. In a wateh-movement, the cmnbination, with a stem-arbor E, an intermediate shift ing head L, a winding-pinion N, and a lever comprising two arms Q, and lit, one 0|. which engages the shitting head, of the spring V for the lover, a swinging yoke '1, having a tooth U to engage the other arm oi. the lever, and the curved spring 'W, extending from the yoke and acting on one arm of the lever, substantially as described.

5. In a watch-movement, the combimitien, with the stem-arbor IE and swinging yoke 'l, of an intermediate shitting head L and the lever comprising the two arms Q and It, for transmitting motion from the stenrarbor to the yoke, substantially as deseribml.

G. In a wateh-movement, the combination, with a handle and a yoke for transmitting motion from the handle to the winding and setting mechanism, said yoke beingprovid ed with a tooth U, o t aleve r Q R, eonneeted to the handle and adapted to engage the tooth IT to move the yoke to the setting position, and a spring \V, extending from the lever to the yoke,said spring when under tension tending to move the yoke to the winding position, substantially as described.

In testimony whereof I have herr'nlnio set my hand and seal. inthe presence of two subseribin witnesses.
